"It was an incredible honour to be asked to document this wonderful event, but also a great privilege to be invited to share and be a witness to this young couple’s love for one another," Lubomirski said in a statement released by Kensington Palace. "I cannot help but smile when I look at the photos that we took of them, such was their happiness together."

This week, the couple joined the royal family for their annual pre-Christmas luncheon at Buckingham Palace.

Markle is also expected to spend Christmas with the royal family at Sandringham, a Palace spokesperson confirmed.
